Insulator-supporting pin



insulator supporting pin is-usually tapered slightly for the purpose of more readily attaching and detaching the same from the conical core of the insulator` body.

ln constructing iny supporting` pin I reduce the diameter of the same in such amanner as to practically make it a spring` at its extremity.

As has been heretofore set forth, the ulti` mate object oi the invention is to provide a supportingpin for an insulating bo'dy of pin type, the pin being` oi' such a flexible and springy character that the insulator body 'will move with the pin when subjected to mechanical stresses and strains by the force oll the wind 'or by pulls or blows. rlhe eilect oi' such strains upo-n the insulator will thus `be greatly minimized and the insulator body will thus be prevented from breakinga down and from being destroyed.

As shown, the insulator body i() is provided with a pair oft tapering1 flanges or petticoats l0 and al', and at the upper portion or" the body is the usual groove or channel o() to form a seat for the reception otl the line wire (not shown) and a groove or channel 5l into which a tie wire (not shown) is iitt'ed to hold the line wire in place upon vthe insulator.

As many 'changes of construction could be made within the scope of my invention, it is intended that all matter contained in the above description or shown in the accompanying` drawings shall be interpreted as illustrative and not ina limiting? sense.

Having now described my invention what l claim as newland desire to secure by Letters Patentis:

l. In a device of the class described, a tapered pin for supporting `an insulator body7 said pin being tapered at one end, and :formed by bending into la springl formation at its tapered end, said formation being' integral.

2. In a device of the ykind described, a supportirug pintor a pin type insulator the lower portion of the pin being rigid, the upbending into a helical tapered coil, the said tapered coil being flexible and springy to bend to any side of the airis of the lower `rigid portion yand being,` integral with said portion.

4l. As an article ot manufacture, an insulator supporting pin, the upper port-ion ot said pin beinp` formed into a tapering` helical coil by bending, the coil portion beingilexible and springy for bodily movement and the lower portion of said pin being iixed and rigid, the structure being integral.

`o. As an article of manufacture, an insulator supporting pin `of tapered form, the end having the largest cross section being rigid and the end having the smallest cross section being' bendable and springy, the said benda-ble springy end being shaped by bendinto a helical tapered coil to for-in screwthreads, the structure being integral.

6. An insulator supporting pin of tapered form, the end having the. largest cross section being rigid and the end havingl the smallest cross section being bendable and sprinpgy, the said bendable springy end being; shaped by bending into a helical tapered coil to form screwthreads, in combination with an insulator body provided with a tapered cavity the wall of which is screwthreaded and in engagement with the turns of the springy helical coil, the pin structure being integral.

ln witness whereof 1 have hereunto set my hand at the borough of Manhattan, city and State of New York, this 23 day of October, i918.
